This looks like a pretty major change, but in reality,
80% of it is just renames of types and corresponding
methods.
The config parsing code has been completely replaced
with a boost::program_options based version. This
means that the config file format slightly changed
(checkout the updated README).
I still expect there to be bugs / unforseen events.
Those should be fixed in follow up commits.
Also, finally reverted back to using pkg-config to
locate and link libruby. Yay for less hacks!
What can I say. I made a pact with the devil, and paid dearly.
Almost a whole day's worth of debugging, actually. Not again.
If this turns out to be slow we can always optimize the critical
parts (with no variable param count) later, or completely remove it.
